Solitary four-wave-mixing states in /spl chi//sup (3)/ media

Summary form only given. Here we present two-parameter coupled spatial solitary solutions where the effective nonlinear shift in the indices of refraction allows three fields to be phase matched for four-wave mixing. The corresponding linear phase propagation constants are for the FWM linear phase mismatch. Even though the linear phase propagation constants generally may not be phase matched for FWM, the total phase propagation constants can be phase matched because of the nonlinear susceptibility.
